Description

Technical Field

[0001] This utility model relates to the technical field of monitoring devices for detecting the thickness of ice accretion on conductors, specifically a monitoring device for detecting the thickness of ice accretion on conductors. Background Technology

[0002] After transmission lines become icy, the overall load on the conductors changes. Using online icing monitoring devices replaces manual line inspections and ice condition assessments, providing timely and accurate location information for de-icing work, thus improving efficiency. Currently available transmission line icing measurement devices are directly installed on the conductors or insulator strings, requiring installation while the line is energized or de-energized, resulting in a large workload and relatively high cost; therefore, the number of installation points is limited. A new method for measuring icing using simulated conductors involves suspending a simulated conductor of the same type and material as the actual conductor on the transmission line tower to simulate icing conditions under the same meteorological conditions. The thickness of the ice is determined by measuring the change in the weight of the simulated conductor, thereby estimating the overall load and ice thickness of the transmission line conductors.

[0003] A search revealed existing technology (application number: CN201920880380.0), which describes a system "comprising a front-end monitoring device, a simulated line assembly, a data acquisition component, and a remote back-end device. The front-end monitoring device, the simulated line assembly, and the data acquisition component are all installed on the transmission line tower. The data acquisition component is used to collect data on the surrounding meteorological environment and weight of the simulated line assembly, as well as to capture images of the simulated line assembly. The front-end monitoring device is used to calculate the thickness of the ice accretion on the surface of the simulated line assembly." This utility model achieves rapid monitoring of icing conditions on transmission lines by replacing traditional transmission lines with a simulated line assembly.

[0004] However, while existing technologies have achieved rapid monitoring of icing conditions on transmission lines by replacing traditional transmission lines with simulated line components, they still have some shortcomings: they can only detect the thickness of the icing, lack automatic de-icing linkage functions, and suffer from response delays that can damage conductors. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a monitoring device for detecting the thickness of ice accretion on conductors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a monitoring device for detecting the thickness of ice accretion on conductors, comprising: a base plate, two sets of support frames fixedly disposed above the base plate, and a support plate fixedly disposed above the support frames, a conductor being arranged between the support frames, and the conductor being connected to the support plate through a tension component arranged on the support plate; The support frame is provided with a shaking component on one side. The shaking component includes a cover arranged on the support frame. The inside of the cover is provided with a movable rod for shaking the wire.

[0007] As a further description of the above technical solution: The tension component includes: The tension sensor is fixedly mounted on the support plate; A pull rod passes through a support plate and is connected to a tension sensor. A collar is connected to the end of the pull rod away from the tension sensor.

[0008] As a further description of the above technical solution: The collar is fitted around the outside of the wire, and the tension sensor is used to detect the tension value of the tension sensor.

[0009] As a further description of the above technical solution: The shaking component also includes: The motor is fixedly arranged inside the casing, and a cam is fixedly arranged at the output end of the motor; The moving rod slides through the cover, and the lower surface of the moving rod abuts against the outer surface of the cam; A spring is arranged in a groove on the machine cover. One end of the spring is connected to the machine cover, and the other end is connected to the moving rod to fix the position of the moving rod.

[0010] As a further description of the above technical solution: The conductor is surrounded by a protective cover, and a support cover is fitted outside the protective cover. The support cover is connected to the end of the moving rod away from the cam and is used to control the vibration of the conductor.

[0011] As a further description of the above technical solution: A controller is fixedly arranged above the support plate, which receives the value from the tension sensor and starts the motor if the specified tension is reached.

[0012] As a further description of the above technical solution: The protective cover and the protective cover are made of silicone rubber.

[0013] This utility model has the following beneficial effects: 1. The wire is fixed by the collar of the tension component. After icing, the weight change is transmitted to the tension sensor through the pull rod. The sensor transmits the signal to the controller to calculate the icing thickness. When the thickness reaches the threshold, the controller starts the shaking component. The motor drives the cam to move the moving rod to shake the wire at high frequency. The spring ensures stable shaking.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1

[0020] like Figures 1 to 3 As shown, the monitoring device for detecting the thickness of ice accretion on conductors provided in this embodiment includes: a base plate 1, two sets of support frames 11 fixedly disposed above the base plate 1, and a support plate 12 fixedly disposed above the support frames 11, and a conductor 3 arranged between the support frames 11, the conductor 3 being connected to the support plate 12 through a tension component 2 arranged on the support plate 12. A shaking assembly 4 is provided on one side of the support frame 11. The shaking assembly 4 includes a cover 41 arranged on the support frame 11. A movable rod 44 is provided inside the cover 41 for shaking the wire 3.

[0021] In this embodiment, the tension component and the shaking component constitute the monitoring device for detecting the thickness of ice accretion on conductors as described in this application.

[0022] It should also be noted that the monitoring device for detecting the ice thickness of conductors in this application can be used for conductors, cables, wires, etc. Figure 1 In this embodiment, the monitoring device for detecting the ice thickness of a conductor is used as an example for description. Of course, other types of monitoring devices for detecting the ice thickness of conductors can also adopt a similar structure, which will not be described in detail below.

[0023] Understandable Figure 1 This illustration only shows some components of the monitoring device for detecting conductor icing thickness. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 The monitoring device for limiting conductor icing thickness detection can also include, compared to Figure 1 More or fewer parts.

[0024] It should also be understood that the tension sensor and controller were purchased from the market and are common knowledge in this field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0025] Furthermore, in this embodiment, the weight of the conductor 3 increases after it becomes covered with ice, and the tension component 2 detects the change in tension. When the ice thickness reaches a threshold, the moving rod 44 of the shaking component 4 shakes the conductor 3, causing the ice layer to fall off. The base plate 1 and the support frame 11 provide stable support, ensuring the reliability of the detection and de-icing process. This achieves real-time monitoring of ice thickness and automatic de-icing linkage, and is compatible with various common diameter conductors.

[0026] Specifically, the tension assembly 2 includes: a tension sensor 21, which is fixedly arranged on the support plate 12; a pull rod 22, which passes through the support plate 12 and is connected to the tension sensor 21, and a collar 23 is connected to the end of the pull rod 22 away from the tension sensor 21.

[0027] In this embodiment, the collar 23 covers the wire 3, and the weight of the wire after it becomes covered with ice is transmitted to the tension sensor 21 through the pull rod 22. The sensor converts the tension signal into an electrical signal and outputs it to complete the monitoring of weight changes. The tension detection response is rapid, and the long-term stability is good. The ice thickness can be calculated from the weight change.

[0028] Specifically, the collar 23 is sleeved around the wire 3, and the tension sensor 21 is used to detect the tension value of the tension sensor 21.

[0029] As a preferred implementation, the collar 23 tightly fits the wire 3 with the fastening bolt, ensuring lossless transmission of tension. The tension sensor 21 continuously monitors the tension change of the wire 3, and triggers a de-icing command when the tension value exceeds a set threshold. This effectively ensures the accuracy of ice thickness calculation and avoids false or missed triggering of the de-icing action. Example 2

[0030] Based on Example 1, in order to further protect the conductor 3 from icing, component 4 is shaken off one side of the support frame 11; Specifically, the shakeout component 4 also includes: The motor 42 is fixedly arranged inside the housing 41, and the output end of the motor 42 is fixedly arranged with a cam 43; the moving rod 44 slides through the housing 41, and the lower surface of the moving rod 44 abuts against the outer surface of the cam 43; the spring 45 is arranged in a groove provided on the housing 41, one end of the spring 45 is connected to the housing 41, and the other end is connected to the moving rod 44, which is used to fix the position of the moving rod 44.

[0031] In this embodiment, the motor 42 drives the cam 43 to rotate, and the eccentric structure of the cam pushes the moving rod 44 to move up and down reciprocally. The spring 45 ensures that the moving rod is always in contact with the cam. The top of the moving rod 44 acts on the wire 3 to generate high-frequency vibration. It has low energy consumption, can work stably in cold environments, avoids mechanical parts jamming, and ensures smooth de-icing.

[0032] Specifically, a protective cover 31 is provided around the wire 3, and a support cover 46 is provided outside the protective cover 31. The support cover 46 is connected to the end of the moving rod 44 away from the cam 43, and is used to control the vibration of the wire 3.

[0033] With this configuration, the moving rod 44 drives the support cover 46 to move up and down. The support cover 46 hits the protective cover 31, and the vibration force is transmitted to the wire 3 through the protective cover, causing the ice to break and fall off due to vibration.

[0034] Specifically, a controller 5 is fixedly arranged above the support plate 12, which receives the value of the tension sensor 21 and then starts the motor 42 if the specified tension is reached.

[0035] The controller 5 receives the signal from the tension sensor 21 and converts it into ice thickness. When the thickness reaches the set value, it outputs a control signal to start the motor 42. The motor shakes for a certain period of time and then stops. The controller re-detects the ice thickness after a certain interval until the tension value drops below the threshold.

[0036] Specifically, the protective cover 31 is made of silicone rubber.

[0037] In this embodiment, the elastic buffering effect of silicone rubber reduces the impact force on the conductor 3 during vibration, avoiding fatigue damage to the conductor caused by hard contact; the low temperature resistance ensures that it maintains elasticity in cold environments and does not become brittle or crack.

[0038] In actual use, the wire 3 is fixed by the collar 23 of the tension assembly 2. After icing, the weight increases and the tension is transmitted to the tension sensor 21 on the support plate 12 via the pull rod 22. The sensor transmits the signal to the controller 5, and the controller calculates the icing thickness.

[0039] When the ice thickness reaches the set threshold, the controller activates the shaking component 4. The motor 42 drives the cam 43 to rotate, pushing the moving rod 44 to move up and down reciprocally. The spring 45 ensures that the moving rod is stably in contact with the cam. The moving rod drives the wire to vibrate at high frequency through the support cover 46, causing the ice layer to fall off. The silicone rubber protective cover 31 reduces the damage to the wire caused by the vibration.

[0040] The support plate 12 is equipped with a controller; the controller is electrically connected to the controller. The controller is the central hub of the entire system, responsible for receiving instructions, monitoring status and controlling the actions of each execution component. Through preset programs or real-time parameter adjustments, the automatic control of the shaking component 4 can be realized. The controller monitors the tension sensor in real time and transmits the sensed signal to the controller, which controls the motor 42 to run.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
